This paper is an effort to utilize abundant availability of natural fibres and waste plastics for the development of composite materials based on polymer and particles of natural fibres for conservation of natural resources such as forests. Ensete false banana (EFB) fibres were used as reinforcement to obtain composit…
Electrohydrodynamic instabilities in poly(3-hexylthiophene) thin films are able to induce uniformly distributed, micrometer scale columns each composed of a spherulite.
The production of electrical energy from nuclear fusions is currently highly advanced field of the interest in an international scientific cooperation in the International Thermonuclear Experimental Reactor programme (ITER). Alloys based on Cu are used in the ITER project however from the future perspective in terms o…
Graphene, a discrete class of nanomaterial, has come into the limelight after its discovery in 2004. Its unique physico-chemical characteristics like electrical, optical, thermal properties and high mechanical strength has piqued the curiosity of the scientific community worldwide. These properties have been utilized…
Lingzhi or Reishi therapeutic fungus, Ganoderma lucidum has been used over the ages as highly medicinal herb in the Orient. We report here a new facet of this “elixir of life” as a mycosource for synthesis of metal nanoparticles. Treating the extracellular suspension extracts of G. lucidum with silver nitrate reduces…
Selecting the proper material and surface treatment methods for elements is one of the essential problems when designing water hydraulic components due to the corrosiveness and poor lubricity of water. Experimental investigation was performed to study the tribological properties of ion-nitrided 2Cr13, a kind of marten…
In the present work, the influence of a gold nanoparticle's shape was investigated on the commercially available Evonik Aeroxide P25. By the variation of specific synthesis parameters, three differently shaped Au nanoparticles were synthetized and deposited on the surface of the chosen commercial titania. The nanopart…
This research investigates and analyzes wear properties of 316 stainless steel before and after applying paste boronizing process and to investigate the effect of shot blasting process in enhancing boron dispersion into the steel. In order to enhance the boron dispersion into 316 stainless steel, surface deformation m…
This study has been conducted to confirm the effect of sacrificial anode cathodic protection system for 90 days to protect corrosion on pier that is located in Korea. The cathodically protected structure was a slab and a pile cap. Before the construction of cathodic protection system, the macrography was carried out.…
Brakovska, Aija (2014): Daphnia Cucullata Sars, 1862 (Crustacea: Cladocera) Distribution And Location In Composition Of Zooplankton Cenosis In Lake Dridzis. Acta Biologica Universitatis Daugavpiliensis 14 (1): 1-19, DOI: 10.5281/zenodo.10601855
Heavy metals contamination threat to the environment is a big concern. Predicting the movement of heavy metals such as Cd in soil is an important goal. In this study the effect of soil chemical and physical properties on Cd mobility were done using a thin layer chromatography (Soil TLC). The soils used in this researc…
Polybenzimidazole (PBI) fibers are produced from polybenzimidazole polymer which has a high thermal and chemical strength with a long chain aromatic structure. These fibers are first used in protective technical textile products due to their good moisture regain and textile performance properties like good hand and dr…
In this paper, energy saving solutions are being elaborated, i.e. A system to harvest waste heat and convert it into electrical energy is presented; such a system is based on thermoelectric generators (teg) modules exploiting the seebeck effect. A technical and economic feasibility study of the system is presented, th…
The effects of BaCu (B 2 O 5 ) doping on sintering characteristics, phase constitute, and dielectric properties of MgZrNb 2 O 8 ceramics were investigated. Results indicated that a small amount of BaCu (B 2 O 5 ) can effectively lower the sintering temperature of MgZrNb 2 O 8 ceramics from 1300°C to 1100°C due to liqu…
Titanium and stainless steel are examples of biomaterials widely used in dental and orthopedic implants owing to their properties of good corrosion resistance and excellent biocompatibility. This paper reports on a study of the biomimetic method applied to titanium (cp-Ti) and 316L stainless steel. The method consists…
The effect of minor element additions (Ca, Al) on microstructural change and magnetic properties of Fe-Nb-Cu-Si-B alloy has been investigated, in this paper. The Fe-Si-B-Nb-Cu(-Ca-Al) alloys were prepared by arc melting in argon gas atmosphere. The alloy ribbons were fabricated by melt-spinning, and heat-treated under…
Atomic-scale elemental maps of materials acquired by core-loss inelastic electron scattering often exhibit an undesirable sensitivity to the unavoidable elastic scattering, making the maps counterintuitive to interpret. Here, we present a systematic study that scrutinizes the energy-loss and sample-thickness dependenc…
This work aims the processing of metal matrix AA2124 aluminium alloy composites reinforced by alumina (Al2O3) and silicon carbide (SiC). The composites were manufactured by powder metallurgy techniques, in a grinding using a ball mill spex type (high energy) at a ratio of balls/ powders of 10:1 and grinding time of 30…
Effect of pretreatments on the graphene coated bipolar plate of proton exchange membrane fuel cell(PEMFC) was investigated in simulated environments for PEMFC by using electrochemical measurement techniques. Interfacial contact resistance(ICR) between the graphene coated bipolar plate and the gas diffusion layer(GDL)…
This paper proposes new types of models that have coaxial magnetic gear (CMG) configurations to increase torque transmission capability. They have flux concentrating structures at the outer low speed rotor, and permanent magnets (PMs) are embedded in the space between stationary pole pieces. The torque performances of…
